COVER INFORMATION Station: URUMQI (Code Ur ) Experiment: Network Monitoring Experiment Exp. Code: N18C3 Schedule Version: 1.00 Processed by SCHED version: 11.50 Development version 11.5. Started Apr. 2 PI: Ross Burns Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596507 EMAIL: burns@jive.eu Fax: Phone during observation: +31-521-596507 Observing mode: Notes: 6cm NME and ftp fringe test for session 3/2018 (512 Mbps, L+R, 2-bit sampling, 2 MHz filters) Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for the 6cm NME and ftp fringe-test on 18th Oct 2018 involving antennas: j2, wb, Ef, Mc, Nt, o8, T6, Ur, tr, ys, hh, Sv, Zc, Bd, Ir, Kunming, Cm, Da, Kn, Pi, De, Ar The NME uses a standard setup with 512 Mbps. The following ftp-fringe tests are scheduled throughout the experiment: 12:15:00 (scan 2, 2 sec, J0956+2515) 12:45:00 (scan 6, 2 sec, J0956+2515) 13:15:00 (scan 9, 2 sec, J1549+0237) 13:45:00 (scan 13, 2 sec, J1549+0237) 14:15:00 (scan 16, 2 sec, BLLAC) 14:45:00 (scan 20, 2 sec, BLLAC) Generally the schedule is split into thirds, the first concentrates on Ar fringe chacking (at the beginnine, at their request), the second aims to confirm fringes to Hh, the thirsd concentrates on the east asian stations. As such, the aforementioned stations will only have two data grabs in which we must fix any problems. So please be alert and ready during your time section if you are one of those stations. Kind regards, and good luck. Ross Schedule for URUMQI (Code Ur ) Page 2 Network Monitoring Experiment UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.
